Meet the demand of client.
Brief description of the drawings
Referring to the drawings, the disclosure will be apparent.It is to be appreciated that these accompanying drawings are only illustrative, not
It is drawn to scale to be also not intended to limit the scope of the present invention.In figure：
Fig. 1 for the present invention compressor and motor attachment structure schematic diagram.
Embodiment
The embodiment of the present invention is explained with reference to the accompanying drawings.
As shown in figure 1, the compressor and the attachment structure of motor of the present invention, include head axle 1 and the driving institute of compressor
The motor of the rotation of head axle 1 is stated, the motor includes motor shaft 7, stator 8, rotor 10, front end flange 5, housing 9, bearing block 12
With rear end cap 16, the stator 8 is fixedly mounted on the inner surface of the housing 9, and its connected mode can use tight fit, described
Rotor 10 is fixed on the motor shaft 7；Offer centre bore 51 on the front end flange 5, the motor shaft 7 is through in described
Heart hole 51；The front end flange 5 and bearing block 12 are fixed on the two ends of the housing 9, the rear end by bolt 6,12 respectively
Lid 16 is fixed on the bearing block 12 by bolt 15；Tapered sleeve 2, the cone are provided between the head axle 1 and motor shaft 7
Set 2 is connected with the head axle 1 by key 4, and one end of the motor shaft 7 offers the cone tank coordinated with the tapered sleeve 2, institute
State tapered sleeve 2 to be placed in the cone tank, the other end of the motor shaft 7 is connected by bearing 14 with the bearing block 13, described
Bearing 14 and the bearing block 13 use interference fits, when needing to pull down motor shaft 7, use the bearing 14 of interference fits can be with
Easily pulled down from bearing block 13.Axially penetrating through for the motor shaft 7 is provided with a stud 11, one end of the stud 11
It is threadedly coupled with the head axle 1, the other end is provided with locking nut 15, the end of the locking nut 15 and the motor shaft 7
Abut, by rotating the locking nut 15, so as to the cone tank of the motor shaft 7 be compressed with the tapered sleeve 2, the torsion of motor
Square passes to head axle 1 by the frictional force between motor shaft 7 and tapered sleeve 2, and can be increased by increasing the pretightning force of stud 11
The peak torque that power-up arbor 7 can be transmitted.
Gap between the stator 8 and rotor 10 is more than between the motor shaft 7 and the centre bore 51 of front end flange 5
Spacing, when motor shaft 7 and the disengagement of tapered sleeve 2, the centre bore 51 of front end flange 5 can hold motor shaft 7, prevent rotor 10 with determining
Son 8 sweeps thorax, destroys the insulating barrier of winding.
Front end flange 5 is bolted on counter flange 3.Counter flange 3 is arranged between compressor and motor.
The rear end cap 16 is fixed on the bearing block 13 by bolt 17, plays a part of sealed motor inner chamber, together
When the bearing 14 can also be played axially position effect.
When needing dismounting motor, motor shaft 7 is dismantled using drawing horse after only rear end cap 16 need to be dismantled.Unclamp lock
Tight nut 15, stud 11 is withstood by the push rod for drawing horse, and now motor shaft 7 is slight to the right moves a segment distance, and tapered sleeve 2 can be with electricity
Arbor 7 is disengaged, and the centre bore of front end flange 5 can hold motor shaft 7 in time, so as to realize the quick of motor shaft 7 and head axle 1
Disengage.Fast quick-detach of the motor shaft 7 in the case of horizontal is realized, after-sale service efficiency is improved, saves the time, reduce
After service cost, greatly meets the demand of client.
As described above, the exemplary embodiments of the present invention are described in detail referring to the drawings.Should
Solution, the present invention, which is not intended to, makes these details constitute limiting the scope of the invention.Without departing substantially from according to this hair
In the case of bright spirit and scope, equivalent or similar change can be carried out to the structure and features of exemplary embodiments
Become, these changes will also fall determined by claims appended hereto in protection domain.
